Your Child Can Do It. So Why Can’t They Do It Consistently?

One of the most frustrating things about parenting a child with big behaviors and emotions is seeing them do something successfully one day and then watching them seem completely incapable of doing the exact same thing the next.
They remembered the entire morning routine yesterday without you saying a word. Today, they’ve walked past their shoes three times while you keep reminding them to put them on.
They sat down and finished their math independently on Monday. On Wednesday, getting started on the first problem turns into an argument.
Their plans changed unexpectedly yesterday, and they rolled with it. But today, a small change to the afternoon schedule sends them into a meltdown.
Once you’ve seen your child do something, it’s easy to think, Okay. So I know you CAN do this.
And they can. The part that gets confusing is why they can do it successfully one day and struggle so much with it the next.
Understanding a little bit about your child’s developing brain can help explain that inconsistency.
Your Child’s Brain Is Doing a Lot More Than You Realize
When we think about brain development, it’s easy to picture a child simply learning more information as they grow.
They learn to read. They learn multiplication. They learn how to tie their shoes and remember their address and tell time.
A huge amount of development throughout childhood also involves your child’s growing ability to manage themselves, their emotions, their attention, and all of the information and demands coming at them throughout the day.
The brain is made up of different areas that contribute to different functions. The temporal lobes are involved in things like language, hearing, memory, and emotion. The parietal lobes help process and integrate sensory information about the body and environment. The occipital lobes are heavily involved in visual processing, and the cerebellum plays important roles in movement, coordination, and balance.
The frontal lobes, including the prefrontal cortex, are especially relevant when we look at many of the behaviors parents are navigating every day.
The prefrontal cortex is heavily involved in planning, organizing, problem-solving, attention, working memory, impulse control, flexible thinking, considering consequences, regulating emotions, delaying gratification, and shifting from what we want to do toward what a situation requires from us.
Think about how many times you expect your child to use some combination of those skills before lunch.
- They have to stop playing and begin school.
- Remember what they need for the lesson.
- Follow several directions.
- Ignore the sibling making noise beside them.
- Keep working when something becomes difficult.
- Tolerate making a mistake.
- Remember what you taught them yesterday.
- Wait while you help someone else.
- Change plans when something unexpected happens.
- Think before saying the angry thing that just popped into their head.
That is an enormous amount of executive functioning, and these abilities are developing throughout childhood and adolescence.
“But I Know They Can Do It”
A developing skill isn’t an absent skill.
Your 8-year-old can demonstrate impulse control. Your 10-year-old can plan ahead. Your 6-year-old can solve a problem. Your 9-year-old can regulate their emotions.
Your child can remember a three-step direction, organize their school supplies, think about how their actions affected someone else, tolerate disappointment, and stop themselves before doing something impulsive.
And then there will be times when they don’t.
We tend to respond differently once we’ve seen evidence that our child is capable of something. If we genuinely believe a child cannot do something yet, we’re usually pretty willing to support them. Once we’ve watched them do it successfully, their inconsistency can start to look intentional.
You’re not trying.
You’re being lazy.
You weren’t listening.
You know better.
You’re perfectly capable of doing this yourself.
When we interpret that inconsistency as a choice, we can easily respond to a child as though they’re refusing to use a skill that may still require support.
A child being able to demonstrate a skill under one set of conditions doesn’t tell us that they’ve mastered it across every environment, emotional state, level of difficulty, or amount of support.
Think about how different it is to organize something you’re excited about versus something you find boring or difficult.
A child might spend an hour planning exactly how they’re going to build something in Minecraft and then seem completely incapable of figuring out what they need to bring to the table for science.
That gives us useful information about the skill. There are conditions under which your child can use it more easily and conditions that place much greater demands on their developing brain. Motivation, stress, distractions, fatigue, familiarity, cognitive load, and the amount of support available can all affect what your child is able to manage in that particular moment.
Instead of stopping at I know you can do this, we can start getting curious about when, where, and under what conditions they can do it.
What Should We Expect From a Developing Brain?
Learning about brain development can bring up a very reasonable question for parents: So what am I actually supposed to expect from my child?
If impulse control is still developing, you still need to teach your child what to do with an impulse.
If executive functioning is developing, your child still needs opportunities to plan, organize, remember, and take responsibility.
If emotional regulation is developing, your child still needs to learn what to do with anger, disappointment, frustration, and overwhelm.
We can expect children to practice planning, organization, problem-solving, emotional regulation, and impulse control while also recognizing that developing skills will still require support, reminders, modeling, and repeated practice.
If your child is developing the ability to organize their work, they need opportunities to organize things.
If they’re developing problem-solving skills, they need opportunities to solve problems.
If they’re learning to tolerate frustration, they need experiences with frustration.
If they’re developing impulse control, they need boundaries and repeated opportunities to practice stopping, waiting, thinking, and trying again.
How much support they need while doing those things will change as the skills develop.
There will be areas where your child is ready for you to step back and allow them to carry more responsibility.
There will be other areas where expecting complete independence leaves them repeatedly failing at something their brain still needs help managing.
This is something we’re constantly adjusting as parents: What can my child meaningfully participate in right now? Where can I step back? Where do they still need structure, modeling, reminders, or co-regulation?
And that answer is going to change as they grow.
Your Response Becomes Part of the Practice
Children develop these capacities through years of using them.
Your child gets thousands of opportunities throughout childhood to wait, remember, plan, organize, recover, solve problems, tolerate disappointment, change course, consider another person’s perspective, and try again.
A lot of that practice happens in relationship with us.
Your child may not be able to solve a problem independently yet, so you help them think it through without immediately solving it for them.
They may struggle to organize a multi-step assignment, so you provide enough structure for them to participate in the planning rather than taking over the entire process.
They may become deeply upset about a boundary, and you continue holding the boundary while helping them move through the emotions that come with it.
As their capacity grows, the amount and type of support you provide can change too. Something that once required you to be heavily involved may eventually need only a reminder, and later your child may manage it independently.
We can’t demand our child’s capacity into existence. Children need opportunities to use developing skills while they still have access to the support that helps them succeed with those skills.
And Then There’s Their Nervous System
This adds another layer to what we’ve been talking about with the nervous system thermometer.
Last week, we talked about how stress changes a child’s access to skills they already have. Now we can consider the developmental capacity underneath those skills too.
When your child is struggling, ask:
How developed is this skill in the first place?
How much access does my child have to that skill right now?
Imagine a child whose impulse control is still developing.
When they’re regulated, they have better access to the impulse control they currently possess. As they become increasingly frustrated, overwhelmed, angry, scared, or dysregulated, using that developing skill becomes harder.
So when a child is at the top of their thermometer and we’re saying, You know better. Think before you act. Use your words. Make a better choice, we may be asking them to rely on a skill that is still developing while their nervous system is also making that skill harder to access.
If a child hits when they become overwhelmed, we still address the hitting while also looking underneath it.
Were they so dysregulated that they lost access to impulse control? Is impulse control itself still a skill that needs more development and support? Was there an unmet need contributing to what happened?
Those answers help us understand what needs attention beyond simply stopping the behavior.
All behavior is communication.
Behavior can tell us about dysregulation, an unmet need, a missing or developing skill, and often some combination of those things. Looking underneath the behavior gives us more information about what our child is struggling to manage and what still needs support, teaching, practice, or development.
Your Child Is Building a Brain
I think we can forget this because we live with our children every day.
We see how smart they are. We hear their surprisingly mature observations. We watch them explain complicated ideas and remember things we’ve completely forgotten.
And then we’re baffled when that same child cannot find the shoes that are directly in front of them or falls apart because their brother touched their pencil.
A child can be incredibly intelligent while still having age-appropriate limitations in planning, working memory, impulse control, emotional regulation, flexible thinking, organization, and all the other skills their developing brain is working on.
We don’t have to wait for those systems to fully mature before asking children to use them. Childhood gives them years of opportunities to practice these skills with gradually increasing independence.
So when you find yourself thinking, I know you can do this, get more specific about what “can” means for your child right now.
How consistently can they do it? Under what conditions? How much support do they still need? What happens to this skill when they’re tired, frustrated, distracted, or overwhelmed?
The answers give you a much clearer picture of what you can reasonably expect your child to manage independently right now, where they still need support, and which skills need more time and opportunities to develop.
